Assuming current spot prices of USD $3.90 per pound for Copper, USD $17 per pound for Cobalt, and USD $1,380 per ounce for Gold. Then these are the Copper equivalent percentages

ECDD002 48m @ 2.18% Cu, 1.97 g/t Au & 619 ppm Co is 48m @3.47% CuEq

ECDD007 46m @ 1.43% Cu, 1.51 g/t Au & 996 ppm Co is 46m @2.64% CuEq

Regardless of the actual dollar prices for each commodity, as long as the price relativities hold, the CuEq should be right. Regardless, they should be a good guide.

I hope this helps.
